IPC: B23P19/00
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To easily identify tension springs by giving identification colors on the end parts of the first tension spring and the second tension spring, which are used for the reel supporting device of an electronic parts supply device. SOLUTION: In the reel supporting device of the electronic parts supply device, the identification colors 51 for identification are given to the end parts of the tension springs 41 and 42. The identification colors 51 are given by paint or color tapes with an appropriate method, for example. The identification colors 51 are constituted to indicate the specification or the features, typically spring constants of the tension springs 41 and 42. The spring constants of the tension springs 41 and 42 are decided by parts reels which are to be installed on the reel supporting device. Thus, the identification colors 51 show the types or the systems of the cassettes of the parts reels. Consequently, assembly work is made efficient since the features of the spring constants of the tension springs are indicated.

IPC: G03G15/08
Filed: 1991-11-20
Abstract: PURPOSE:To prevent defective developing from being execute by replenishing toner so that it does not drop around a to sensor when it IS replenished to a developing roll part from hopper. CONSTITUTION:A shielding member 24 is arranged at the upper part of a replenishment magnetic roll 18 in the hopper 20. When the toner is replenished to the developing roll 12 part from the hopper 20, one part of the replenishing toner is shielded by the shielding member 24 and it does not drop around the toner sensor 16.

Title: Bearing detecting apparatus
Inventor: OKAMOTO KENJI
IPC: G01C19/38
Filed: 1989-12-21
Abstract: PURPOSE:To adjust the deviation of the amplification factor of an amplifier automatically and to make it possible to detect a correct bearing by switching the output of the amplifier to the output of the amplifier having the next lower amplification factor from the first amplifier when the digital value from an A/D converter is saturated. CONSTITUTION:The output of a gyroscope 1 is amplified in amplifiers 21 and 22 having the different amplification factors. The outputs of the amplifiers are switched with an input switch 3 in a time series. For example, when the digital value from an A/D converter 4 corresponding to one amplifier 21 is saturated, the output is switched to the output of the amplifier 22 having the next lower amplification factor than the amplifier 21, and the output is used. Therefore, the output of the amplifier which is not saturated and has the highest sensitivity can be utilized all the time. The output whose digital value is not saturated from the A/D converter 4 is stored. When either digital value from the A/D converter 4 are saturated and the output is switched to the amplifier having the next lower amplification factor than the first amplifier, the gain of the amplifier after the switching can be corrected with a control part 54 by using the stored output value of the amplifier before switching and the stored output value of the amplifier after the switching.
